David Davis says he feels vindicated over the government's decision to scrap its absurd plan to detain terror suspects for 42 days - once touted by the so-called political cognoscenti as the make-or-break issue that would define Gordon's premiership. And so he should.
Meanwhile it is reasonably clear that, for all his obvious intellectual firepower, Dominic Grieve lacks the political clout to shadow a major office of state.
The conclusion ought to be an obvious one for David Cameron: Restore David Davis to the Shadow Home Secretaryship forthwith. Not only would it be right and proper in view of his 42-day triumph, it would also steal some of Brown's thunder in the wake of his astonishing yet still widely-applauded decision to appoint his most implacable political enemy as Business Secretary.
Will Cameron will have the balls to do it? I'm not holding my breath...
